Ted Kremenek 8e7fbcc3e4 [static analyzer] Tweak RetainCountChecker's diagnostics to correctly indicate if a message was due to a property access. This can
potentially be refactored for other clients, and this is a regression from the refactoring of property acceses.

Richard Trieu 5d1aff049e Change the checks in the type aka printing. A confusing case where the string
of the first type is the same as the aka string of the second type, but both
types are different.  Update the logic to print an aka for the first type to
show that they are different.

Richard Smith ce40ad677e Represent an APValue based on a Decl as that Decl, rather than a DeclRefExpr
or MemberExpr which refers to it. As a side-effect, MemberExprs which refer to
static member functions and static data members are now emitted as constant
expressions.

Argyrios Kyrtzidis b97a4025ff [PCH] When completing an objc forward reference, do not serialize the chain of its categories because
it is going to be rewritten (and the chain will be serialized again), otherwise we may form a cycle in its
categories list when deserializing.

Also introduce ASTMutationListener::CompletedObjCForwardRef to notify that a forward reference
was completed; using Decl's isChangedSinceDeserialization/setChangedSinceDeserialization
is bug inducing and kinda gross, we should phase it out.

Fixes infinite loop in rdar://10418538.

Douglas Gregor 80b6904baf Implement a minor optimization when loading module maps to satisfy a
module import: don't re-check for a loaded module unless we've
actually loaded a new module map file. Already-loaded module map files
aren't interesting.

Douglas Gregor af28ec80a3 When searching for a module, speculatively load module maps to see if
the module is described in one of the module maps in a search path or
in a subdirectory off the search path that has the same name as the
module we're looking for.

Douglas Gregor 88bdfb0ed9 Teach the search for modules to consider modules described by a module
map, so long as they have an umbrella header. This makes it possible
to introduce a module map + umbrella header for a given set of
headers, to turn it into a module.

There are two major deficiencies here: first, we don't go hunting for
module map files when we just see a module import (so we won't know
about the modules described therein). Second, we don't yet have a way
to build modules that don't have umbrella headers, or have incomplete
umbrella headers.

Douglas Gregor ab0c8a849a Wire up the mapping from header files mentioned in module maps over to
the corresponding (top-level) modules. This isn't actually useful yet,
because we don't yet have a way to build modules out of module maps.

Douglas Gregor 718292f260 Introduce basic support for parsing module map files.
Module map files provide a way to map between headers and modules, so
that we can layer a module system on top of existing headers without
changing those headers at all.

This commit introduces the module map file parser and the module map
that it generates, and wires up the module map file parser so that
we'll automatically find module map files as part of header
search. Note that we don't yet use the information stored in the
module map.

Richard Smith e97cbd7b3a Constant expression evaluation: support for constexpr member functions. This
reinstates r144273; a combination of r144333's fix for NoOp rvalue-to-lvalue

caused.

This patch also adds support for some additional forms of member function call,
along with additional testing.

Richard Smith 4a905b6799 Implicit casts from rvalue to lvalue are not meaningful. Don't accidentally add
them when performing a const conversion on the implicit object argument for a

No change to the testsuite: the test for this change is that the added
assertion does not fire any more.

Ted Kremenek 20be0b4397 [static analyzer]: only call RemoveDeadBindings() when analyzing non-Expr stmts, entering a basic block, or analyzing non-consumed expressions. This sigificantly speeds up analysis time, and reduces analysis time down to 27% less than before we linearized the CFG.

John McCall f4beacd059 Whenever explicitly activating or deactivating a cleanup, we
need to provide a 'dominating IP' which is guaranteed to
dominate the (de)activation point but which cannot be avoided
along any execution path from the (de)activation point to
the push-point of the cleanup.  Using the entry block is
bad mojo.

John McCall e63abb5d2b Fix a subtle bug with cleanups: when activating
a previously-inactive cleanup, not only do we need a
flag variable, but we should also force the cleanup to
query the flag variable.  However, we only need to do
this when we're activating in a context that's
conditionally executed;  otherwise, we may safely
assume that the cleanup is dominated by the activation
point.
